Megan Fox admits she's mentally unstable in a new magazine interview -- and could end up dying young like one of her icons.

"I basically read every book ever written about Marilyn Monroe," Fox, 23, tells the September/October issue of Wonderland. "I could end up like that because I constantly struggle with the idea that I think I'm a borderline personality -- or that I have bouts of mild schizophrenia. I definitely have some kind of mental problem and I haven't pinpointed what it is."

In the same story, Fox slams her Transformers director Michael Bay again. (After she called the action flick "not about acting," earlier this summer, Bay bit back that she "says some ridiculous things" in July.)
